IMPROVEMENT IN UNIVERSAL-GEARED JOINTS The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concer-n.:

Be it known that I, G, F. GREEN, of Kalamazoo, in vthe county ot' Kalamazoo, and State of` Michigan, have invented a'new and improved Universal-Geared J oint; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, making a part of this specification. y

Figure l is a. perspective view of the geared joint.

Figure 2 is a. detachedlview of gear, sleeve, and an'- nular segment.

Figure 3 is a similar view of' gear, segment-guide, shaft, and set-screw. f

Similar letters of reference indicate corresponding parts in `the several figures.

The nature of my invention consists in so forming the teeth on two gear-wheels, that when properly set and held in position, by means of an annularsegment, as will be hereafter described, they will move together freely at any desired angle. l

lhe object of my invention is to construct a universal joint `which will be capable ot' transmitting motion from a,l driving-shaft, in any, combination vof machinery, at any desired angle, and which may either he set and heldin any position, or allowed to change the angle while in motion, as the case may require.

It may be used on the tumbling-rod of' a threshingmachine, and alson a bit-brace or drill-stock, for boring or drilling at lany angle, and for lall other purposes where such a joint may be .found useful.

To enable others skilled in the art to understand and construct my invention, I will describe its coustructiou and operation.

Fig. 1, H H represent two gear-wheels, the teeth of which arelike common spur-gear, with the exception of the peculiar shape. They project on one end so as to form a half circle,.equal in diameter to the depth of' the tooth, and are tapered toward the opposite end of the gear, nearly to the base ot' the tooth. v

A is the sleeve, or tubular bearing, in which the shaft of one of the gearfwheels revolves.

B isau annular segment, tirmlyattached to the vsleeve A. Y

Eis the sleeve in which the driving-shaft G revolves.

To the under side ot' E is attached a' guide, F, with a chamber turned in it, fitting closely -to the segmentV B, which is set in such a position that its centre is located in the pitch-line at the point of contact of the gears H H, thereby permitting the gears to r'un freely together, at any angle within a halt' circle.

The gears H H are held in any desired position by the set screw G pressing segment B.
